A holding member 7 is formed at a plurality of locations, and has a substantially arc-shaped engagement portion 6 formed at the upper end for rotatably holding the protrusion 4 of the panel frame 3, and is inserted into each of the insertion holes 5. The holding portion +47 is fixed to the instrument main body 1 with a set screw 8, and the protrusion 4 of the panel frame 3 is fixed.
It has a structure in which a through hole 9 is formed in the base of the panel frame 3 into which the engaging portion 6 of the holding member 7 is inserted when the panel frame 3 is opened. With the structure of this device, when inspecting the lamp installed in the device body 1 or replacing it due to its lifespan, the panel frame 3 is opened as shown by the chain line in FIG. The part 4 is rotated into engagement with the bearing recess 2 of the instrument body 1, and the front opening of the instrument body 1 is opened for inspection or for replacing the lamp. The engaging portion 6 of the holding member 7 (4) is inserted into the through hole 9 formed at the base of the protrusion 4, and the panel frame IA3 is inserted into the panel frame IA3 when the panel is replaced or replaced. To remove the panel frame 3, loosen the setscrew 8 as shown in FIGS. The body 3 is disengaged from the protrusion 4, the protrusion 4 of the panel frame 3 is removed from the bearing recess 2 of the instrument body 1, and the panel frame 3 is removed.

(Problems to be Solved by the Invention) In the structure of the conventional device shown in FIGS. 5 and 6 above, the insertion hole 5 is provided at the base of the bearing recess 2 of the device body 1 and the protrusion 4 of the panel frame 3 is provided. Through-holes 9 must be drilled in the base in post-processing, resulting in poor processing efficiency, and light leakage occurs from the storage through-holes 5 and 9.
Is it exposed to the outside? If the panel frame 3 is removed due to loss of +Q properties, if the panel frame 3 is listened to closely, the engaging portion 6 of the holding member 7 will engage with the through hole 9 of the panel frame 3, and the panel frame 3 will be removed. Since the body 3 cannot be removed, it is necessary to insert your hand into the narrow opening with the panel frame 3 slightly past 1 gram and loosen the setscrew 8. Furthermore, even if the holding member 7 is raised, it will fall due to its own weight. Easy to remove the panel frame 3 from the instrument body 1 while holding the holding member 7 in the upper position by inserting your hand through the narrow listening angle with the panel frame 3 slightly open. However, there was a problem with poor workability.

The present invention solves the above-mentioned problems, and therefore does not expose the pivot parts such as hinge fittings that attach the panel frame so that it can be opened and closed, or separate holding members, thereby improving the appearance and making the panel frame larger. To provide a lighting fixture that allows the panel frame to be removed in a listening state, allows easy attachment and detachment of the panel frame, and can be assembled at low cost without the need to form insertion holes or through holes that cause light leakage. It is something to do.
